Nonlinear waves of a surface charge at a curved plasma boundary

Abstract

The nonlinear behavior of the surface charge has been analyzed for the curved plasma boundary. Detail descriptions of the solitary surface wave motion are obtained for the cold uniform plasma occupying a spherical volume with immobile ions. Some features of nonlinear azimuthally symmetric circle oscillations are revealed for half-space plasma. The dependence of the nonlinear structure of the surface charge on a shape of the time-varying curvature of the plasma boundary is found in the case when some deviations occur on the plasma surface. Substantiations of optimal conditions of carrying out are presented for specially aimed interactions of the electromagnetic radiation with some features of plasma surface distortions and processes caused by the occurrence of these perturbations.
